Safety Precautions Before installing the unit, thoroughly read the following safety precautions. Observe these safety precautions for your safety. WARNING This symbol is intended to alert the user to the presence of important instructions that must be followed to avoid the risk of serious injury or death. CAUTION This symbol is intended to alert the user to the presence of important instructions that must be followed to avoid the risk of serious injury or damage to the unit.
PAGE 3
WARNING Securely attach the terminal block cover (panel) to the unit. After completing the service work, check for a gas leak. If the terminal block cover (panel) is not installed properly, dust and/or water may infiltrate and pose a risk of electric shock, smoke, and/or fire. If leaked refrigerant is exposed to a heat source, such as a fan heater, stove, or electric grill, poisonous gases may be produced.
PAGE 4
Precautions for handling units for use with R410A CAUTION Do not use the existing refrigerant piping. Use a vacuum pump with a reverse-flow check valve. A large amount of chlorine that may be contained in the residual refrigerant and refrigerating machine oil in the existing piping may cause the refrigerating machine oil in the new unit to deteriorate. R410A is a high-pressure refrigerant and can cause the existing pipes to burst.
PAGE 5
Before installing the unit WARNING Do not install the unit where a gas leak may occur. When installing the unit in a hospital, take appropriate measures to reduce noise interference. If gaseous refrigerant leaks and piles up around the unit, it may be ignited. High-frequency medical equipment may interfere with the normal operation of the air conditioner or vice versa. Do not use the unit to keep food items, animals, plants, artifacts, or for other special purposes.
PAGE 6
Before installing the unit (moving and reinstalling the unit) and performing electrical work CAUTION Properly ground the unit. Periodically check the installation base for damage. Do not connect the grounding wire to a gas pipe, water pipe, lightning rod, or grounding wire from a telephone pole. Improper grounding may result in electric shock, smoke, fire, and/or malfunction due to noise interference. If the unit is left on a damaged platform, it may fall and cause injury.
PAGE 7
Before the test run CAUTION Turn on the unit at least 12 hours before the test run. Do not operate the unit without panels and safety guards. Keep the unit turned on throughout the season. If the unit is turned off in the middle of a season, it may result in malfunctions. Rotating, high-temperature, or high-voltage parts on the unit pose a risk of burns and/or electric shock. To avoid the risk of electric shock or malfunction of the unit, do not operate switches with wet hands.

[ I Read Before Servicing ] [1] Read Before Servicing I Read Before Servicing 1. Check the type of refrigerant used in the system to be serviced. Refrigerant Type Multi air conditioner for building application CITY MULTI YJM-A series R410A 2. Check the symptoms exhibited by the unit to be serviced. Refer to this service handbook for symptoms relating to the refrigerant cycle. 3. Thoroughly read the safety precautions at the beginning of this manual. 4.
PAGE 13
[ I Read Before Servicing ] [2] Necessary Tools and Materials Prepare the following tools and materials necessary for installing and servicing the unit. Tools for use with R410A (Adaptability of tools that are for use with R22 or R407C) 1. To be used exclusively with R410A (not to be used if used with R22 or R407C) Tools/Materials Use Notes Gauge Manifold Evacuation and refrigerant charging Higher than 5.
PAGE 14
[ I Read Before Servicing ] [3] Piping Materials Do not use the existing piping! 1. Copper pipe materials O-material (Annealed) Soft copper pipes (annealed copper pipes). They can easily be bent with hands. 1/2H-material (Drawn) Hard copper pipes (straight pipes). They are stronger than the O-material (Annealed) at the same radial thickness. The distinction between O-materials (Annealed) and 1/2H-materials (Drawn) is made based on the strength of the pipes themselves.
PAGE 15
[ I Read Before Servicing ] 4. Thickness and refrigerant type indicated on the piping materials Ask the pipe manufacturer for the symbols indicated on the piping material for new refrigerant. 5. Flare processing (O-material (Annealed) and OL-material only) The flare processing dimensions for the pipes that are used in the R410A system are larger than those in the R22 system. Flare processing dimensions (mm[in]) A dimension (mm) R410A R22, R407C ø6.35 [1/4"] 9.1 9.0 ø9.52 [3/8"] 13.2 13.0 ø12.
PAGE 16
[ I Read Before Servicing ] [4] Storage of Piping 1. Storage location Store the pipes to be used indoors. (Warehouse at site or owner's warehouse) If they are left outdoors, dust, dirt, or moisture may infiltrate and contaminate the pipe. 2. Sealing the pipe ends Both ends of the pipes should be sealed until just before brazing. Keep elbow pipes and T-joints in plastic bags.
PAGE 17
[ I Read Before Servicing ] [6] Brazing No changes have been made in the brazing procedures. Perform brazing with special care to keep foreign objects (such as oxide scale, water, and dust) out of the refrigerant system. Example: Inside the brazed connection Use of oxidized solder for brazing Use of non-oxidized solder for brazing 1. Items to be strictly observed Do not conduct refrigerant piping work outdoors if raining. Use non-oxidized solder.
PAGE 18
[ I Read Before Servicing ] [7] Air Tightness Test No changes have been made in the detection method. Note that a refrigerant leak detector for R22 will not detect an R410A leak. Halide torch R22 leakage detector 1. Items to be strictly observed Pressurize the equipment with nitrogen up to the design pressure (4.15MPa[601psi]), and then judge the equipment's air tightness, taking temperature variations into account. Refrigerant R410A must be charged in its liquid state (vs. gaseous state). 2.

[ I Read Before Servicing ] [8] Vacuum Drying (Evacuation) (Photo1) 15010H (Photo2) 14010 Recommended vacuum gauge: ROBINAIR 14010 Thermistor Vacuum Gauge 1. Vacuum pump with a reverse-flow check valve (Photo1) To prevent the vacuum pump oil from flowing into the refrigerant circuit during power OFF or power failure, use a vacuum pump with a reverse-flow check valve. A reverse-flow check valve may also be added to the vacuum pump currently in use. 2.

[ I Read Before Servicing ] [9] Refrigerant Charging Cylinder without a siphon Cylinder with a siphon Cylinder Cylinder Cylinder color R410A is pink. Refrigerant charging in the liquid state Valve Valve liquid liquid 1. Reasons R410A is a pseudo-azeotropic HFC blend (boiling point R32=-52°C[-62°F], R125=-49°C[-52°F]) and can almost be handled the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder in the liquid phase.
PAGE 21
[ I Read Before Servicing ] [11] Characteristics of the Conventional and the New Refrigerants 1. Chemical property As with R22, the new refrigerant (R410A) is low in toxicity and chemically stable nonflammable refrigerant. However, because the specific gravity of vapor refrigerant is greater than that of air, leaked refrigerant in a closed room will accumulate at the bottom of the room and may cause hypoxia. If exposed to an open flame, refrigerant will generate poisonous gases.
PAGE 22
[ I Read Before Servicing ] [12] Notes on Refrigerating Machine Oil 1. Refrigerating machine oil in the HFC refrigerant system HFC type refrigerants use a refrigerating machine oil different from that used in the R22 system. Note that the ester oil used in the system has properties that are different from commercially available ester oil. Refrigerant Refrigerating machine oil R22 Mineral oil R407C Ester oil R410A Ester oil 2.

[ VIII Test Run Mode ] [1] Items to be checked before a Test Run VIII Test Run Mode (1) Check for refrigerant leak and loose cables and connectors. (2) Measure the insulation resistance between the power supply terminal block and the ground with a 500V megger and make sure it reads at least 1.0Mohm. Do not operate the unit if the insulation resistance is below 1.0Mohm. Do not apply megger voltage to the terminal block for transmission line. Doing so will damage the controller board.
